Take a break from breakfast: If you’re not hungry, feel free to skip breakfast and just have coffee (with some milk if you want it). Many people find that within a few days of eating low-carb, high-fat meals, cravings and hunger decrease significantly. This can make it easy to skip a meal, perhaps especially breakfast. Skipping a meal is cheap, fast, and might increase the diet’s effectiveness for weight loss and diabetes. See intermittent fasting
As for if you’re dealing with health issues, you really have to defer to your doctor. For instance, if you have kidney disease, you also want to talk to your doctor about appropriate protein intake. If you have heart disease, you can still go low carb, but you may be better off opting for monounsaturated fats (avocados, nuts, and olive oil) over saturated fats (butter and red meat). Everyone’s cholesterol levels respond differently on a low-carb diet, so if yours are going up, switch to unsaturated sources of fats, Spritzler recommends. “In general, this is a diet most people can do. If you have a chronic condition, work with a doctor who understands low-carbohydrate diets to monitor you,” she adds.
If you treat your diabetes with insulin or any other medication that puts you at risk of hypos (low blood sugar levels), following a low-carb diet may increase this risk. Speak to your healthcare team about this so they can help you adjust your medications to reduce your risk of hypos. Your team may also support you to check your blood sugar levels more often. 
That said, there isn’t an agreement that a low-carb diet is superior to any other kind of diet or that it’s healthier long term. A review in the December 2015 issue of Diabetes Therapy that looked at the diet among those with diabetes noted that when it comes to weight loss, a low-carb diet performs no better than other higher-carb diets; and that it doesn’t produce better glycemic control, either. (5) Another report in Diabetes Care also found that over one year, those on a low-carb diet lost weight faster than those on a low-fat one, but after a year, weight loss and A1C levels (an average of blood glucose over about three months) were remarkably similar.

Severely restricting carbohydrates to less than 0.7 ounces (20 grams) a day can result in a process called ketosis. Ketosis occurs when you don't have enough sugar (glucose) for energy, so your body breaks down stored fat, causing ketones to build up in your body. Side effects from ketosis can include nausea, headache, mental and physical fatigue, and bad breath.
You probably hear the most about low-carb eating for weight loss, but for some people, the approach could also help optimize their health, says Schmidt. “Research shows that women who are obese or have metabolic problems [may] do better hormonally on lower carbs,” says Schmidt, pointing out that other outcomes of the diet can include better sleep, mental clarity, and increased satiety.

Natural fats and high-fat sauces: Using butter and cream for cooking can make your low-carb foods taste better and can make you feel more satisfied. Try a Béarnaise or Hollandaise sauce. If purchased pre-made, check the ingredients for starches and vegetable oils. Better yet, make it yourself. Coconut fat or olive oil are also good options. Learn more


Once your body is fat adapted, you can then consume a little less fat at every meal and let your body burn what it needs for energy from your fat stores. This can help you lose weight. If at any time you feel deprived, unsatisfied or have cravings, add fat back into your diet. Listen to your body. If you consume more fat than your body needs, it may slow down your fat loss. If you eat too little fat, however, you may feel tired, grumpy and hungry. Your body will tell you what it needs. Learn to listen to its cues again.
"Your body will often shift metabolism when you do something different to it -- but it equalizes -- you see a rapid shift and a return to normal -- and the longer-term studies show normal results in this area," says Sondike. Still, he tells WebMD it's a "smart idea" to take a calcium supplement beginning at the start of your low-carb diet to safeguard against a possible deficiency. Tofu can also be a good source of calcium.
However, there’s no evidence that following a low-carb diet is any more beneficial in managing diabetes than other approaches in the long term, including a healthy, balanced diet. Research suggests that the best type of diet is one that you can maintain in the long term, so it's important to talk to your healthcare professional about what you think will work for you. Another option is the Mediterranean diet, which is also linked to reducing the risk of heart diseases and stroke.
